[Eeglablist] Problems with scripting

[arno]

Dear Michael,

thank you for your email. About the graphic crashes, I do not really 
know. We have Opterons 64-bits and we are running I think Fedora (Kernel 
is 2.6.9-22.EL) and Matlab SP3 and it works fine.
About your scripting problem. There is indeed sometimes a problem with 
the pop_chanedit function about importing channel location files from 
the command line (it is usually about looking some electrode location up 
not about loading them though). I have attached the updated function. 
The referencing problem might be a consequence of that too? Please let 
us know at eeglab at sccn.ucsd.edu if it works.

Best regards,

Arno
